Novel imidazole derivatives of the formula:
wherein
R1 is lower alkyl or, phenyl-C1-2alkyl which may be substituted with halogen or nitro;
R2 is lower alkyl, cycloalkyl or, phenyl which may be substituted with halogen, lower alkyl, lower alkoxyl or di (lower alkyl) amino,
one of R3 and R4 is of the formula: -(CH2)n,-COR5 in the formula
R5 is amino, lower alkoxyl or hydroxyl and n is integer of 0,1 or 2, and the other is hydrogen or halogen; provided that R1 is lower alkyl or phenethyl when R3 is halogen, n is 1 and R' is lower alkoxyl or hydroxyl, and their salts have hypotensive activity.
